e Be itknown that I, EDWIN }'[..'BELL, a citizen of` the United States,residing at Chicago, county of Cook, State of Illin ois,'have in- 5vented ka `certain new and useful Improve- 1- ment in Railroad-Ties andl deelarethe followingto be a full,'clear, and exact descri tion of theinvention, such as will enab e others skilled inthe art to whichitpertains ro to make and use the same', reference being v -had totheaccompanying drawings, which form a part` of this specification.

My invention relates in gen P'ral to railroadties`,and.mor eparticularly to tirs made of a 15 compositi on of materials. i T eincreasing scarcity of timber renders the use o i" wooden railroad-tiesquite expenv ,sive,l especially as theyare of comparatively short lifeand have to be replaced by new ones 2o after a few years usage, The.primary, bject of my invention is to Iprovide aconiposition railroadtiewhich will i cstinitially little more than a wooden tie ',fand will bedurable and elicient in use. l 25 inventiongenerally described, consists,inga metallic core, preferably of 4V-shaped crossfsection, surroundedby and v,embedded -in cement, rail-'clam s resting upon the core;aidengagingthe rai base, the latter prefer- 3o lymgbelow the surfaceofthe cement being supported directly upon the metallic core'. f

My invention willjbe more fully described v'he/reina' erwithtreference tov theaccompany-v drawings, inwhich the salneisillustrated "as embodied. in two convenient and practical forms,Y and inwhichf f 'Figure lis a lan view; Fig. 2 a crossfsec- `Jtional view on 5ine 2 2j, Fig. 1.; Fig, alonziotudinal sectional view online 3 3, Figs..1 and 2; -"Fig. 4`, an elevational view, arts being broken away, of amodilication; Fig. 5, aplan view of the modified' form of my inventionshownin Fi 4; and Fig. 6, a sectional viewon line 6, ig. 4.

and is rovided with a numberof openings i7 threug the two portionsthereof in order that when the tie is 4formed by'surrounding the corewith the plastic cement the lattermay ass freely to the space within thecore, thereby insuring the complete embedding of the core within thecement and :filling every portion of the space 'within the core withlthe cement.

When the core occupies a position in which the two members thereotEdiverge upwardly,l as shownv in Figs. 1, 2, and 3, ythe edges of the twomembers are flush with the ripper suriace oi the tie, as shown in Figs.1- andi2. The portions of thertie above which the rails 7o et the trackextend are countersunk and the two membersv of the core-bent inwardly to`form flanges, as shown in Fig. 2, upon which the base of the rail isdirectly supported.v

ln order that the rail may be readily and securely fastened to the tie,clamp-plates D andl)2 are provided, which are located within therecesses in the top or" the tie at either side of the rail-base. Theclamp-plates are provided with tapered portions, which overlie the basec of the rail C, as clearly shown in Fig.Y 3, thereby immovablyfastening the rail toy the tie. The claming-plates'arefof 1 such a widththat they Wil rest upon and be supported by the inturned flanges b ofthe core B. Any suitableimeans may beprovided .for securing the clampin-plates to' the tie-such, for instance, as bo ts E and E2, y .the headsofwhich are received in recesses vin the clamping-plates andWhiclrextenddowm' 9o wardly through openings in the core anden- .terinto engagement with screwthreaded Washers e and e, located. at thebottom .of

` the tie. Such. washers may conveniently'be embedded in the plasticcement when the tiev 95 is made.

vIn Figs. 4, 5, and 6 I have shown a modi-l fied embodiment of myinvention in which the V-shaped core B2 is so located that the members'thereof diverge downwardly, as shown in Fig. 6.A In this embodiment ofmyinvention the eountersunk portions at the top of the tie to receive thebases ofthe rails extend below the apex of the core, which is cut awayto form a seat for'the rails and selcuring-clamps. In this modifiedembodiment of my invention, as in the embodiment thereof iirstdescribed,the base of the rail is 4 directly supported upon the metallic coref, asare also the retaining-clamps D and D, so n IOO .the openings l)therethrough and with the seats to receive the rail-base'andretainingclamps, after which the cement m plastic -form is molded aroundthe core to impart to the tie the desired cross-section. After thecement has hardened the tie is ready for use and may be laid upon theroad-bed in the customary manner. The rails are then placed upon theties with their bases located within the countersunk portions thereofand resting directly upon the metallic' cores. The clamping-plates arethen placed in position and the bolts turned through the screwthreadedwashers at the bottom of the ties, thereby causing the clamping-platesto forcibly engage the bases of the rails.

.F rom the foregoing description it will be observed that I haveinvented an improved railwf'iy-tie which may be readily constructed andto which the rails may be easily and securely fastened and which willnot deteriorate by usage, as it is in no wise injured by the moisturewhich destroys wooden ties 'and will, through its substantialconstruction, withstand the wear and tear to which railroad-ties aresubjected by the constant pas-` sage of trains over the rails supportedthereupon.

While I have described more or less precisely the details ofconstruction, I do not wish to be understood as limiting myself thereto,as I contemplate changes in form and the proportion of parts and thesubstitution of equivalents as circumstances may suggest or renderexpedient without departing from the spirit of my invention.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a railroad-tie, the combination with a body portion of cement, ofa metallic core of substantially V-shaped cross-section eme bedded inthe cement in an inverted position.

2. In a railroad-tie, the combination with a body portion of cement, ofa substantially V-shaped core embedded in the cement in an invertedposition, said core having holes therein through which the cement whenplastic passes to the space between the members of the core.

3. In a' railroad-tie, the combination-with 4a body portion of cement,of ametallic core embedded therein, and seats formed in the core belowthe up er surface of the tie for supporting the rai s.

4. The combination with a railroad-tie, of a body portion of cement, aV-shaped metallic core embedded therein, the top of said core extendingflush with the upper surface of the tie, and seats formed below the topof the core for supporting the rails.

5. In a railroad-tie, the combination with the body portion of cement,of a substantially V shaped metallic core embedded therein, seats formedin the upper surface of the tie and extending below the to of the core,and clampingplates locate within said seats for engagmg the basesf ofthe rails.

6. In a railroad-tie, the combination with the body portion of cement,of a substantially V-shaped metallic core embedded therein, seats formedin the upper surface of the tie and extending below the top of the core,clamping-plates located within said seats for engaging the bases of therails, bolts engaging said clamping-plates and extending throuvh thetie, and screw-threaded washers embedded inthe under surface of the tiethrough which said bolts y ass.

In testimony whereof sign this specification in the presence of twowitnesses.
